Hi, Rainer -

If you haven't already, one thing to try in such circumstances is to
try a subscriber listserv command to see if their server will
acknowledge you and send you an email response, to see if that gets
through:

        To check being subscribed:  Send email to LISTSERV AT VM.MARIST DOT EDU
                                    containing the command:  CONFIRM ADSM-L

(Your postings are being distributed and archived, so you are still in
the list.)

Then...

        To check your settings:  Send email to LISTSERV AT VM.MARIST DOT EDU
                                 containing the command:  Query ADSM-L

See if the settings indicate no email, in any way.  If everything
looks right, you might try toggling your settings to digest...

      set adsm-l DIGEST

and a bit later return to normal:

      set adsm-l NODIGests

and see if that resolves the problem.  If not, check for any kind of
filtering at your site, conferring with your email administrator to
check the mail server logs for any sign of incoming from Marist for
you.  If no sign of incoming at your site, it may be that Marist is
having mail server issues that they have yet to perceive.  You could
send email to their postmaster or other prospective address to try to
get someone there to track down the problem.
